ConceptMap search

Overview

GET /fhir/{version}/ConceptMap returns the HL7 FHIR-to-OMOP Implementation Guide ConceptMaps that OMOPHub hosts - gender, encounter class/admit-source/discharge-disposition, condition status, allergy/intolerance categories, immunization route/source, vital signs, blood pressure, vaccine, and clinical-findings maps. These back the $translate url parameter (see $translate) and let IG-driven tooling discover the maps by canonical URL.

Targets use FHIR R4 equivalence on /fhir/r4/ and /fhir/r4b/, and the R5 relationship code on /fhir/r5/ and /fhir/r6/.
